DEVICEOPERATION
Themodesof operationsof theM27C405arelisted
in the OperatingModes table. Asingle power sup-
plyis requiredin the read mode.All inputsare TTL
levels except for V
pp
and 12V on A9 for Electronic
Signature.
Read Mode
The M27C405 has two control functions, both of
which must be logically active in order to obtain
data at the outputs.Chip Enable (E) is the power
control and should be used for device selection.
OutputEnable(G) is the outputcontroland should
be used to gate data to the output pins, inde-
pendent of device selection. Assuming that the
addresses are stable, the address access time
(t
AVQV
)isequalto thedelayfromEtooutput(t
ELQV
).
Datais availableat theoutputaftera delayof t
GLQV
from the falling edge of G, assuming that E has
been low and the addresseshave been stable for
at least t
AVQV
-t
GLQV
.
Standby Mode
TheM27C405hasa standbymodewhichreduces
the active current from 30mA to 100
μ
A. The
M27C405is placedin the standbymodeby apply-
inga CMOShigh signaltothe Einput.When in the
standbymode,theoutputsareinahighimpedance
